The AuroraVision northern lights forecast for Iceland uses real-time data from NOAA's Space Weather Prediction Center, updated every 2 minutes. Our visibility score combines solar wind direction (Bz), speed, particle density, magnetic field strength, and local cloud cover into a single number from 0–100%.
Iceland is one of the best places in the world to see the northern lights. Located at 63–66° north latitude, Iceland sits directly in the auroral oval — the ring around Earth's magnetic pole where aurora activity is highest. Even at low KP levels (2–3), aurora can be visible from dark rural areas across Iceland.

Five data points that determine aurora visibility
Southward Bz (negative) is the single most important trigger — it opens a "door" in the magnetosphere for solar particles to enter.
Higher speed (>500 km/s) compresses the magnetosphere and increases particle injection. 700+ km/s is associated with strong aurora.
Total interplanetary magnetic field strength. A stronger Bt amplifies the effect of southward Bz.
Proton density (p/cm³) of the solar wind. Higher density means more particles available to excite the atmosphere.
Clear skies are essential. Cloud cover data from Open-Meteo, specific to each Icelandic location.
Best viewing window is 22:00–02:00 local time in Iceland (GMT+0 in winter, GMT+1 in summer). Astronomicaldarkness is required — aurora is invisible before the sky is fully dark. Check conditions 1–2 hours before heading out, as solar wind data updates every 2 minutes and conditions can change rapidly.
